Identification of super cells in radar echo based on moment invariants theory
Pages: 346-350
Year: Issue:  4
Journal: Journal of Chengdu University Of Information Technology

Keyword:  多普勒天气雷达数字图像处理超级单体不变矩;
Abstract: 根据超级单体在反射率因子图中的强度信息、水平尺度、典型的钩状回波等特征,利用图像处理技术对多普勒天气雷达回波图中超级单体进行识别,从而更好地为天气预报服务.首先通过图像分割获取灰度图中超级单体的结构,然后结合轮廓跟踪法和贴标签的方法对目标进行区域分割,获取目标存在区域,最后基于不变矩具有对位移、尺度和旋转变换的不变性对目标进行识别.仿真结果表明该方案可行且具有良好的识别性能.
